Please Parse...

[tripod1]

Please parse "A few grab weightless underwater arm". I have an answer of "Tentacle" but cannot parse. Thanks in advance.

Ten tac(k)le

[Fitzer]

Ten = few
Tackle - k (kilogram) = grab

[bobbinwales]

ten + tackle minus K???? ....although should be Kg so maybe am wrong

[JimF]

It's not a brilliant clue. K would indicate temperature or potassium, not weight.

[bobbinwales]

or a 1000 generally.
We wondered about maybe the missing g (for gravity) gives the weightless but could'nt make that work

[Neveracrossword]

K, kilo, is in Chambers, so seems OK?

[ichkeria]

K can stand for kilo(s)
It’s still pretty unfair though.
And tentacles don’t have to be underwater

[bobbinwales]

not convinced, but kilo just means a 1000 - we run 5k so k can also mean kilometresbut, tho a can see were more likely to say weighs 30 kilos than ran 30 kilos.

[ichkeria]

It is in the dictionary but Kg is the more common abbreviation for the actual weight. I suspect what is really meant is it’s short for the prefix kilo-
Collins dictionary does give kilos as an option though

[Neveracrossword]

Ichkeria, Chambers seems to cover both - k - kilo or kilo-'.
